To all 11:]: o m, it In o concern:

Be it known that I, ALBERT Goon), citizen of the United States of i imerice, rcsiiling at tlrand Rapids, in the county of Kent and State of Michigan, have invented cor ain new and useful Improvements in lVeather-Strips;- and I do hereby declare the following to he a full, clear, and exact tie" scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the some.

My invention relates to improvements in weather strips and more particularly to weather strips for windows, and its object is to provide the same with various ne and useful features hereinafter more full described and particularly pointed out in the claims, reference being had to the accompanying drawings, in which:

Figure l is a horizontal section showing a portion of the sash and casing with my in vention applied thereto. Fig. 52 isan enlarged detail of a portion of the weather strip proper. Fig. 3 a perspective of. a portion of the fixed member of the weather strip, and Fig. 4' the same of a movable member of the same.

Like numbers refer to like parts in all 0 the figures.

1 represents a portion of the casing, 2 and 3 the edge of the respective sash members of a Window, 4 and 5 the stops on the casing.

In the edge of the sash adjacent the ing and nearest to the side toward the opposite sash is a grioovo 6 in each sash to receive the slidahly engaging members of the weather strip. The fixed member 7 is secured at one edge under one of the stops and extends opposite the edge of the sash and nearly across the same to the groove. This furnishes a wide strip secured at one edge only and havingconsiderable flexibility to permit the sash to shrink and swell without objectionable frictional resistance between the movahleand stationary parts. The free edge of this strip 7 bent at right angles to extend into the groove in the sash is thence returned upon itself forming a channel U-shaped incross section, with its paral lel sides spaced apart to receive a smaller U- V shaped portion of a sheet metal member 9 consisting "of a strip of thin SllHGllIllGltll sccured to the sash and moved therewith.

This member 9 has one edge secured to the 5 sash andv extends across the remaining edge portiol'i of the same and is fixed thereto and thus ma ses with the sash when the same is moved to open and close the window, and also horizontnllwif the sash shrinks and swells. A portion 10 of this strip is folded in U-shape and considerably smaller than the edge 8 or" the strip 9 whereby it runs freely within the same.

The base or convex edge of the U-shaped portion 10 engages the concave side of the portion R and. slides freely thereon. The resilience of the broad portion 7 attached to the casing maintains yieldable connection between the Ushaped portions, and the side clearance therehetween and also the clearance between the portion 8 and the walls of the groove permits free movement of the sash in both directions without binding contact and at the same time the air is effectively cxcliuled from passing the edge of the sash regardless of the amount of clearance between the some and the casing and stops. The air entering this clearance from. either direction must, in order to get through, pass into the groove hy traversing around on the outside of the portion 8 and thence return in the opposite direction between the two U-shapcd portions 8 and it). In this return movement there is no clearance between the convex side of the portion 10 and the concave side of the portion 8. These two ion tions having a rocking movement upon each other and also being yieldably held in contact by the resilience of the strip 7, will always he in contact and prevent further pas sage of the air in either direction and thus secure a complete stoppage of the air passage, and at the same time provide a weather strip that will readily conform to the shrinkage and swelling of the sash and clearance between the some and the casing and stops without in any wise interfering with its etiective operation and easy sliding movement when the sash is raised or lowered.

Yi'litt I claim is? l. 1 weather strip for windows compris ing strips 0' sheet metal each having one edge formed into U-shape, one U-shape portion being smaller than the other and hav .ing rocking and sliding movement on the lai-ger ushape portion.

'2. A weather strip, comprising two sheet metal strips each bentat right angles near one edge mid thence formed in U-shapes of unequal dimensions, the smaller U-shaped portion being slidable within the larger and out of contact therewith except at the convex base portion of the same which portion engages the concave base portion of the other strip, said strips being respectively attached near their other edgesrespectively to a Window casing and to a window sash.

3. In a combination with a windowsash having a groove in its edge, and a window casing, two strips of sheet metal each bent substantially at right angles to extend with in the groove and each bent in U-shape within the groove, said bent portions being of different dimensions, the smaller U- shaped portion slidable within the larger U-shaped portion and spaced therefrom at its parallel sides and also engaging the concave portion of the larger one at its convex base portion and slidable therein.

4'. A weather strip for windows comprising strips of sheet metal each having one edge formed into U-shape, one U-shape portion being smaller than the other and hav-' ing rocking and sliding movement on the larger U-shape portion at one side only thereof.

5. The combination with a sash having a groove in its edge and a casing for the sash, of a, weather strip consisting of two sheets of strip metal one of whichis secured at one edge to the casing and at its opposite edge bent into U-shape with the Ushape portion extending into said groove, the other strip also being bent at one edge to form a U- shape portion which extends into the U-shape arate strips of sheet metal secured to the window frame and window, respectively, the adjacent ends of said strips being bent into U-shaped formation, one of'said U-shaped portions being smaller than the other and having its bight portion only contacting with the corresponding sight portion only of the other strip for sliding engagement therewith and its side portions spaced from the side portions of the said U-shaped member of the other strip, whereby a rocking movement thereon is permitted.

In testimony whereof I affix my signature in presence of two Witnesses.
